Sometimes, all you need to have fun with a class for another few months is a few new ideas to tinker around with. Class Expansions is a series of lightweight supplements for The Pathfinder Roleplaying Game that takes a base class and offers alternative class features that, handily enough, each fit on one page or less.
Following in this vein, Class Expansions: Oracle Mysteries introduces two new mysteries for the oracle base class.
